CIGAR-BUNCH MACHINE.

Application filed February 7, 1925. SeriaI No. 7,483.

()ur invention relates to an improvement in cigar bunchmachines and moreparticularly to an improvedreaper.

In cigar bunchmachines of the automatic. type, provided with anintermittent filler feeding device, such, for example, as formsthesubject-matter of the U. S. Letters Patent granted to Meyer Bayuk No.1,538,082 dated May 19, 1925, there is required some means, as a reaper,for removing the fillers from the feed, positioning them for trimming bythe corrugated knives and placing them in the filler transfer.

The handling of the fillers, as by the reaper, presentsa'problem of somecomplication, since the fillersinust be taken from the feed, positionedfor trimmin and after they are trimmed passed to the fil er transfer andat the same time always keeping the tiller under control so as toprevent the tobacco forming the filler from separating. To retain thefillers in the form in which they are entered in the feed by theoperator, it is found necessary to maintain a certain amount of pressureon the fillers during their movements bythe reaper and while they arebein trimmed.

Now it is the objectofour invention to provide reaping mechanism towithdraw the fillers from the feed, position them for trimming andenterthem in a transferring device without loss of form.

Further objects of our invention are to provide a reaper which will behighly efiicient and durable in operation and at the same time simple inconstruction and free from the necessity for complicated or frequentadjustment.

Having now indicated, in a general way, the nature and purpose of ourinvention, we will proceed to a detailed description thereof withreference to the accompanying drawings, in which we have illustrated apreferred embodiment, and in which-- Fig. 1 is a sectional viewof aportion of a cigar bunch machine showing a part of a reaper and itsoperating mechanism in accordance with our inventlon.

Fig. 2 is a sectional view similar to Fig. 1 showing a reaper embodyingour invention, in association with a filler feeding device.

Fig. 3 is a plan viewof the subject of Fig. 2.

a filler feeding device comprising a pair of endless chains 11 passingover suitable sprocketsd and to which are secured transversely extendingbars 0, each serving to support a plurality of spaced clips or fingers fbeneath which a filler h is adapted to be placed by an operator. Thechains 0 are driven intermittently in a step-by-step manner from asprocket 7} on-' a driven shaft j, through a chain is engaged with asprocket Z loosely mounted on a shaft m which carries sprockets nengaged with chains 0. The sprocket l is intermittently connectedwithshaft on through the engagement of a spring-pressed pawl o carried bysprocket Z in one of four notches g in a disc 7* keyed to shaft m. Ad-

jacent the disc 7' and loosely mounted on shaft m. is a cam disc 8having a cam surface cutin its periphery and adjustably secured to asupport t by mean'sof bolts passing through arcuate slot at in thesupport. A pin 1) extends laterally from the pawl 0 and rides on theperiphery of cam disc 8 and controls the entry of pawl 0 into notches gin disc 1'. The/pawl is allowed to enter a notch g when the pin ridesinto the cut-out portion in the periphery of the cam disc and is liftedout of the notch when the pin rides out of'th'e cut-out portion. WVhilethe pawl is in a notch g, the shaft m will be turnedand the chains 0 andfingers f advanced. The time of entry of the pawl into a notch and thedistance the feed is ad-. vanced is determined by adjustment of the camdisc 8, aswillbe obvious from inspection of Fig. 7.

' At the end of the feeding device thereis struction for trimming andcutting out the ends of the tiller prior to the application of thebinder.

Above the strips w are a plurality of ski bars 3 secured adjacent theirrear ends to a cross member 2 pivotally mounted on trunnions 2. A bar 3extends transversely of the ski bars and is adapted to be lifted,against the action of a weight 5 suspended from it, by means of lovers-11 actuated by cams 6 connected with the forwardipair of feed chainsprockets (Z to raise the ski bars and permit them to fall under theinfluence of weight 5 for the purpose to be hereinafter explained.

Adapted to be operated between the strips '10 are a series of spacedreaper fingers 8 turned up at the rear ends as at 9 and provided withheel portions 10 at the forward ends. The fingers 8 are mounted on across member 11, which is supported by the turned-up ends of a pair ofparallel supporting bars 12. Adjacent the ends of the bars which supportthe lingers, the bars are longitudinally slotted, as at 7, for thereception of the ends of a. pin 13 passing through a knuckle 14 on oneend of a lever 15, the other end of which is pivoted to the frame of themachine. The opposite ends of the bars 12 are pivotally secured to ablock 16 slidably mounted in slots formed in brackets 17 supported fromshaft m and the frame of the machine. The lever is adapted to beoscillated by means of a cam disc 18 mounted on a shaft 19 and on theside of which is formed a cam surface 20 adapted to be followed by a camfollower 21 carried by the lever. The rods 12 are adapted to bereciproeated through the medium of connecting rods 22 pivotallyconnected to the block 16 and to the cam wheel 18 and to corresponding,crank disc 18 also mounted on shaft 19. Thus, it will be observed thatif the wheels 18 and 18 be rotated the rods 12 will be reciprocated andoscillated and the cam surface 20 being properly designed the reaperfingers 8 supported on the ends of rods 12 will be moved from theposition shown in full lines, F ig. 1, longitudinally of the strips 10to the position shown in dotted lines, Fig. 1, then donwwardly,longitudinally and upwardly again to the position shown in full lines,Fig. l.

Secured to disc 18' is a sprocket wheel 23 over which passes a chain 24engaging a sprocket wheel 25 mounted on a shaft 26, an adjustable idlersprocket 27 being provided for adjusting chain 24.

The shaft 26 is adapted to be intermittently driven by means of a smallgear 28 mounted on the shaft and a large gear 29 mounted on a shaft jwhich is continuously driven, as shown in Fig. 1. The gear 29 isprovided throughout part of its periphery with teeth and is partlyblank, as indicated, the ends of the section being beveled off asindicated at 30. The periphery of the small gear 28 is also providedwith a blank section. The gear 29 is continuously rotated and while itsteeth are in mesh with the teeth of gear 98, the gear 528 is driven.However, in the rotation of the gears, the blank section of gear 28meets the blank section of gear 2!) and the blank section of gear 28will ride thereon. hen the end of the blank section of gear 29 isreached due to the bevel, indicated at 30, the teeth of the two gearswill mesh and gear 28 will be again driven.

If now it be assumed that the clutch coir trolling the actuation of thefiller feeding device and the relationship of the gears 28 and 29 bearranged so as to properly time the actuation of the filler feed andreaper, the operation of the device will be simply explained.

Referring to Fig. 2, assuming the feed to be at rest, the reaperactuating mechanism has just come into operation and the reaper fingersare raised with their upturned rear ends 9, behind a, filler 71 in theclamps f, and the heel portions 10 behind a filler 71.: The reaper moveslongitudinally draws the filler h from the feed and pushes the filler 7!into the jaws of a. transfer device 31. When the filler 71 is entered inthe transfer, the filler It will have been positioned over the dies 0:,with which a cutter cooperates. The reaper then rests and the cutteroperates and the jaws of the transfer device close. The reaper fingersthen are moved rearwardly, downwardly and upwardly, during which thefeed device moves, to come to rest as the reaper fingers move upwardlyto a position to withdraw a filler.

The ski bars are normally yieldingly held by weight- 5 so as to bear onthe fillers 7: and h under the control of the reaper, their forward endsbeing lifted by cams 6 to permit the feeding device to advance a fillerto the position shown in Fig. 2.
